At what age does remaining a virgin start to get weird? Am I a lost cause?

I was picked on around 12/13 for being fat and was designed to die a lonely virgin (no romantic relationships).

I lost weight and women noticed around 17/18 but I did not do anything at all. I was terrified. I had to remain stoic. I have had 10-15 girls directly ask me out and approach me.

It has stopped since I stopped going to university. Now years later and working a minimum wage job, I offer nothing of value.

My sister even somehow found out I was a virgin and started bullying me.

I feel defective. Like no one wants to deal with a manchild virgin boy who is almost 30 years of age.

What do you think? Should I give up? Is it hopeless?
